Ovata, paulo depressa, nigra, protliorace elytrisque (maculis 

 exceptis) rufis, maculis 2 prothoracis disco, 2 humeralibiis et 1 magna 

 scutellari ; capite vix dentato, haud profnnde punctato ; prothorace 

 uudique disperse punctato ; scutello fere impunctato ; elytris 

 subtiliter lineato-punctatis ; pygidio punctato, cum pedibus longe

This insect, with its bright red upper surface and five 

 large black spots, is quite unmistakable. Except in the 

 tarsi the three specimens, representing both sexes, which 

 I have examined are identical, although Dejean's example 

 is somewhat immature and has the spots and lower 

 surface reddish. 



I have already pointed out that the species called 

 hicolor, Westw., by Dr. Ohaus belongs to this group, 

 whereas the true P. hicolor, Westw., belongs to the 

 "rufopicta group." The former should therefore be called 

 P. femorata, Burm. According to Dr. Ohaus it is very 

 variable, but the male is chiefly red and the female 

 generally quite black. 



The following is nearly allied to P. nigripennis, Sharp, 

 regarded by Dr. Ohaus as a variety of P. femo^xda, but as 

 the British Museum possesses a fairly large series of 

 specimens from three different collections, showing practi- 

 cally no variation, it must be regarded as a permanent 

 form. The two sexes are alike except in the structural 

 character referred to.

This insect is black with the exception of the prothorax 

 and parts of the legs ; whereas P. nigrijyennis is described 

 as red with the exception of head, elytra and markings on 

 the less.
